Description

Implantable medical device remote monitoring system and method

technical field

The invention relates to the field of implantable medical systems, in particular to a remote monitoring system and a remote monitoring method for implantable medical devices.

Background technique

Implantable medical devices (IMD) usually include implantable electrical nerve stimulation systems (including deep brain electrical stimulation DBS, implantable cerebral cortical electrical stimulation CNS, implantable spinal cord electrical stimulation SCS, implantable sacral nerve electrical stimulation SNS, Implantable vagus nerve stimulation VNS, etc.), implantable cardiac electrical stimulation system (commonly known as cardiac pacemaker), implantable drug infusion system (IDDS).

Taking the implanted electrical nerve stimulation system as an example, it mainly includes a pulse generator implanted in the body, electrodes and external control devices. Among them, the pulse generator is connected to the electrode, so that the pulse generated by the pulse generator is transmitted to the electrode, and the pulse signal generated by the pulse generator is transmitted from the electrode to the heart or specific nerve parts for electrical stimulation, so that the human body function returns to normal state of operation. External control devices include doctor programmers and patient controllers.

Among them, the patient controller is a device equipped for the patient to control the switch or adjust the output parameters of the pulse generator in the body according to his own situation. Usually, the patient can only adjust himself within the adjustment range set by the doctor. The doctor's program controller is a device used by the doctor to control and adjust the output parameters of the pulse generator in the body according to the patient's condition. Usually, one doctor's program controller can be used to control multiple pulse generators. The patient controller and doctor programmer can communicate with the pulse generator through wireless communication mode, magnetic coil or other communication methods.

During the implantation operation of the pulse generator and the treatment process after implantation, it is necessary to adjust the stimulation parameters of the pulse generator. The current program control process is performed and completed by the doctor in front of the doctor. .
